14 Backpack Strap Pocket and Pouch Options - Built-In and Modular
So, you want a backpack with pockets on the straps? The bad news is that this convenient little feature isn’t as common as we would like. The good news is that you still have some options!
In this buying guide, we have researched what is available and have included some of our favorite backpack designs that feature pockets in the shoulder straps, as well as some modular backpack strap pouch options. Whether you need a secure place to store a Metro Card or quick access to your smartphone, there is something for you.
What are the options?
Built-In: Backpack Shoulder Strap Pocket

Backpacks with strap pockets aren’t common, but they can be found if you look hard enough. The main limitation with built-in strap pockets is that most shoulder straps are thin, limiting the size of the pocket. Some brands have creative solutions, like stretchy pockets for phones, but the majority of built-in strap pockets are only large enough to fit small flat items such as a credit card or cash.
Modular: Backpack Strap Pouch

If you want a shoulder strap pocket that can fit larger items like a large cell phone, a small notebook, or earbuds, your best bet is to go with an add-on shoulder strap pouch. These pouches are much larger than built-in shoulder strap pockets and offer more versatility in terms of what you can carry.
You can either buy into a modular backpack system, meaning a backpack brand that offers different modular shoulder strap pouches and pockets, or stick with the backpack you already own and choose a universal strap pouch. In this buying guide, we offer options for both.
Shoulder Strap Pocket Backpacks
Pacsafe Metrosafe X Anti-Theft
Designed for optimal anti-theft security, the Pacsafe Metrosafe Anti-Theft Commuter Backpack will give you the ultimate peace of mind during busy commutes. While the most important pockets are located on the inside, it's the exterior of the backpack that offers the most wow-factor. You have a main compartment with an integrated lock, puncture-resistant zippers, and even the ability to lock the entire bag to a table or chair leg to prevent grab-and-run theft in public spaces.
The common backpack shoulder strap pocket is a small slip pocket for quick access to small items, but the Pacsafe Metrosafe Commuter goes a step further and offers a full zip design for an added layer of security. Here you can stash away small items like earbuds or a metro card and know they're going to be safe and sound during your daily commute.
Able Carry Thirteen Daybag
Small but mighty, the Able Carry Thirteen is a highly water resistant backpack that keeps you organized without the bulk. Along with a protective 13” laptop sleeve, you have plenty of dedicated spots to stash essentials like keys, chargers, and a water bottle.
The Able Carry Thirteen Daybag is easily one of our favorite backpacks with secret compartments, and two of those compartments are located inside the shoulder straps. Each shoulder strap is equipped with a small slip pocket that can fit small, flat items like metro cards, IDs, and credit cards. It makes a night out in the city safer and your public transportation trips a breeze.
SwissGear ScanSmart Backpack
The SwissGear ScanSmart Laptop Backpack is a highly versatile bag designed to keep up with your busy daily routine and travel needs. It offers a crazy amount of compartments for optimal organization, a lay-flat compartment for easy TSA scans, and a bottom shoe compartment for the ability to separate your packing.
If you are specifically looking for a backpack with a cell phone pocket on the strap, then you are in luck. What sets this backpack apart is the built-in power bank pocket in the laptop compartment that allows you to route a charging cable to the outside of the pack. Store your phone inside the shoulder strap pocket, and now you have an integrated system for staying charged on the go!
Osprey Arcane Large Day
Designed for everyday commuting and busy days on campus, the Osprey Arcane backpack is equipped with features to make life just a little bit easier. Inside the main compartment, you are greeted with an organization panel for your laptop, chargers, keys, and other daily essentials.
One of our favorite design features of the Arcane backpack is all of the discreet low-profile pockets that can be found around the outside of the bag. On one side of the pack, you’ll find a low-profile stretch water bottle pocket that stays against the bag for a cleaner look when not in use, while a stretchy strap pocket is located on the right shoulder strap for easy access to small items you need quick access to, such as earbuds or transportation cards.
FENRUIEN Expandable Laptop Backpack
The Fenruien Business Expandable Backpack is for both, well, you guessed it, business and travel. Its secret weapon is an expandable compartment that allows for a slim 26-liter daily carry size on workdays and an impressive 38 liters of packing room when expanded for travel packing. Other awesome features include laptop and tablet sleeves, a USB-C charging port, and plenty of pockets for organization.
This backpack also has a hidden strap pocket for cards. It’s a great spot for those identification and public transportation cards you need quick access to, and a built-in zipper keeps it nice and secure.
Modular Systems: Backpack Strap Pouches
Think of a modular backpack system as an ecosystem of backpacks and accessory attachments that flawlessly work together. Once you own the bag, you can start mixing and matching extra pouches and accessories to expand your carry. There are a few brands that offer these kinds of systems, but for shoulder strap pouches and pockets, the ones we feature below are our favorites.
Chrome Industries Backpacks + Accessory Pouches
Chrome is known for their highly water-resistant and tough-as-nails backpacks (no, seriously, these bags are built like tanks) for daily carry and commuting. We are partial to the Chrome Barrage Cargo for its rugged construction and cool colorways, but the brand offers a ton of great designs to fit your needs.
Whether you are looking for a backpack strap pouch for your phone or easy access to a pen and small notebook, Chrome offers a few great modular add-ons that can be purchased separately and are designed to attach specifically to their backpack straps. You can also use the pouches as standalone organizer storage and toss them inside the pack. These little pouches are built as rugged as their backpacks and we wouldn’t except any less from Chrome.
Chrome Tech Accessory Pouch
Chrome Phone Pouch
The Chrome Tech Accessory Pouch is large enough for all your little bits and bobs like a pen, charging cable, small notebook and a phone. Need a fast way to access your phone? Check out their Phone Pouches that can attach to any Chrome backpack strap.
Alpaka Elements Backpack + Modular Ad-Ons
If you are looking to enter an ecosystem of modular backpack strap pouches and accessories, then Alpaka is where you want to look. The Alpaka Elements Pro is a compact urban backpack with an emphasis on organized daily carry. This is achieved by Alpaka's growing number of modular attachments that allow you to add special pockets where you need them for smarter carry.
Alpaka gives you the option to build a collection of the HUB Ecosystem of magnetic accessory attachments or go with modular pouches that can be attached to the shoulder straps of the Alpaka Elements Pro Backpack. No matter what you need to carry, Alpaka offers a solution for everything from ID badges to earbuds and phones.
Alpaka Modular Phone Sling
Alpaka Modular Sling
Our favorite Alpaka backpack strap pouch has to be the Metro Pouch, a compact pouch for everyday essentials like earbuds, transportation cards, and small EDC tools. The Metro Pouch can be attached to a backpack strap or any one of Alpaka's various sling bags. A close second is the Alpaka Modular Sling, which includes a strap so you can carry the pouch as a standalone sling bag but can also be attached to a backpack strap. Inside, you'll be able to store valuables like a phone, passport, and tech.
Topo Designs Backpacks + Accessory Pouches
When people think of modular bags, Topo Designs usually doesn’t come to mind, but the truth is that the brand offers a great range of backpack designs that can be used with add-on shoulder strap pouches.
What’s great about Topo Designs is that their backpack collection ranges from affordable daily packs to higher-end American-made backpacks, allowing you to pick your poison according to your budget.
Topo Designs Taco Bag
Topo Designs Mountain Accessory Bag
Our favorite Topo pouches are the Taco Bag and Mountain Accessory Bag. Both of these pouches can be attached to backpack shoulder straps using the built-in clips and are large enough for small essentials like AirPods, cash, and cards.
Mission Workshop Arkiv Modular Backpack System
As far as modular backpacks go, the Mission Workshop Arkiv System offers some of the best, thanks to their incredible construction and innovative features. The Arkiv System gives you the option of a few different sized base backpacks and allows you to add as many accessories as your heart desires, so that you can build the perfect pack from the ground up. Some of their shoulder strap attachments include a phone pocket and utility pocket for tools and small essentials.
Universal Backpack Strap Pouches
If you don’t want to purchase a new backpack then universal shoulder strap pockets are always an affordable option. These ad-on pouches allow you to attach a strap pocket to a backpack you already own.
The only requirement with many of these is that your backpack straps should already have a horizontal loop or tab for attachments.
Clakit Phone Strap Pack
The Clakit Phone Strap Pack is as close to a universal strap pouch as you’ll get, thanks to its innovative wrap-around clip that allows you to attach the pouch to nearly any backpack strap. Inside, you’ll be able to fit a phone for easy access when you are on the move.
BOOSTEADY Backpack Strap Pouch
The BOOSTEADY Backpack Strap Pouch is a large and affordable pouch for storing essential items that you need quick access to. Inside, you’ll be able to store items like a phone, small notebook, pens, and chargers thanks to its internal mesh pockets.
To use this backpack strap pouch, you’ll need a pack with a horizontal attachment loop to secure the pouch. Although most tactical backpacks have MOLLE attachments on the straps for compatibility, some daily backpacks also have something similar, so you should check your backpack before purchasing.
REI Co-Op Packmod Rainshield Pocket
The REI Rainshield is a shoulder strap pocket that can be attached to any backpack that has horizontal attachment loops. What makes this pocket special is its weatherproof seam-taped nylon construction that makes it perfect for commuting and backpacking, where keeping your gear dry is key. Inside, you can fit a phone, map, snacks, or whatever else your heart desires!
